Old joke: A scientist has a good-luck horseshoe hanging over the door to their lab. A visitor to the lab says to them “Surely you don’t believe in superstitious nonsense like that?”; the scientist replies “Of course not; but, I am told it works even if you don’t believe in it.”
New joke: An atheist goes to church and joins in enthusiastically with the hymns and prayers. Their friend says to them “I thought that you didn’t believe in all of that religious stuff?”; the atheist replies “I don’t; but, I am told it doesn’t work even if you believe in it.”
